Yelawolf does it pretty well.
Ha! Ha! Ha! Yellawolf is not considered Country-Rap. Now to answer the question, I personally approve. For me, it is just a fun, new-ish subgene of Country and Rap. Say what you want about it, e.g., the two genres not meshing together or whatever, but it has it followers like me.
Plus there is this: Colt Ford is the first person to have an album go #1 on Billboard's Top Country Albums Chart when Declaration Of Independence topped the chart the week of August 25th, 2012 and also have an album go #1 on Billboard's Top Rap Albums Chart with Thanks For Listening for the week of July 19th, 2014.
Now, I wouldn't say that the Rap fans were the ones that help get Colt #1 on the Rap Charts, as I would say it was the "New Age Country Fans" that did so, as that is the general market for his albums. I kind of think that, and please correct me if I am wrong, that Rap fans (ones that would call rap their favorite genre) probably find it to be garbage that an artist like Colt Ford is even eligible for Billboard's Rap charts.
